ibora..


Recommended Posts

A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora’s extinction.

 

Which of the following, if true, most seriously weakens the argument above?

(A) The drug made from ibora bark is dispensed to doctors from a central authority.

(B) The drug made from ibora bark is expensive to produce.

© The leaves of the ibora are used in a number of medical products.

(D) The ibora can be propagated from cuttings and grown under cultivation.

(E) The ibora generally grows in largely inaccessible places.

 

Folks, your inputs pls.

 

 

Thanks,

Arun B

Agree with 'D'

 

The issue here is "continued production of the drug must inevitably lead to the ibora’s extinction'...so in order to keep the drug flow continue and at the same time have the plant growth in tact we need some reason to suggest plant can be prosperd elsewhere to weaken the argument..That's what 'D' is suggesting. 'E' is not even focussing on real issue.

how the drug is dispensed doesn't help or hurt whether the tree becomes extinct

 

(B) The drug made from ibora bark is expensive to produce.

how expensive is out of scope

 

© The leaves of the ibora are used in a number of medical products.

using the leaves still doesn't prevent the tree from becoming extinct

 

(D) The ibora can be propagated from cuttings and grown under cultivation.

using the trees cut down can help grow more trees, sounds great to me

 

(E) The ibora generally grows in largely inaccessible places.

sounds like growing back the trees that were cut is going to be a pain

 

IMO D
